For decades, investors have eagerly awaited Berkshire Hathaway's quarterly 13F filings to see where the "Oracle of Omaha" is deploying capital. Here is your complete guide to tracking Warren Buffett's stock portfolio in 2026.
Every quarter, institutional investment managers with over $100 million in qualifying assets must file a Form 13F with the Securities and Exchange Commission (SEC). This filing reveals their U.S. equity holdings, providing a transparent (albeit delayed) look into the portfolios of the world's greatest investors.
No 13F is watched more closely than Berkshire Hathaway's. When Buffett buys or sells, the market pays attention. Our live Berkshire Hathaway tracker automatically ingests these filings so you can monitor his portfolio's evolution.
While Berkshire Hathaway's portfolio holds over 40 different stocks, the vast majority of its value is concentrated in a tight group of high-conviction "pillars".
